The VCR Tutor: Effective Instruction for Device Operation

摘要: A critical issue for intelligent tutoring systems (ITS) is whether knowledgeable diagnosis and feedback offers instructional benefits compared with less knowledge-intensive methods. The effectiveness of different methods examined in a device operation task: setting VCR to record program. Four simulations use approaches emphasizing specific types knowledge. possibility acquiring this knowledge manipulated by increasing opportunities interact the simulation explicitly providing feedback. Eighty novice adults were randomly assigned four tutors training. Planned comparisons learner achievement indicate greater learning correctness Analysis variance (ANOVA) detect predicted linear trends shows increased across versions. Results are not simply function differences trainin...
